About

I am a Master's student in Electrical and Computer Engineering at Johns Hopkins University, focused on backend engineering, AI agents, and data-driven applications.

Recently, I built a Medical RAG Agent featuring ReAct-based tool use, short- and long-term memory, hybrid retrieval, and PostgreSQL-backed medical record workflows. Previously, as a Software Engineer Intern at Datalynn, I developed asynchronous scraping pipelines that processed more than 180,000 rows per day and increased throughput by 4×.
